APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday November 13, 2003 (MJD 52957) ---=== OBSERVING TEAM ===--- Swing: Atsuko Kleinman Night: Steph Snedden, Pete Newman ---=== OBSERVING PLAN ===--- Shakedown tests and science if possible. ---=== OBSERVING SUMMARY ===--- Rain prevented opening. ---=== OBSERVING LOG ===--- Afternoon: Norm placed an extra dewar inside the enclosure as the weather is poor and we did not want anyone hurt trying to get a new dewar to the enclosure during the night. The enclosure is a bit crowded with the pump used to pump down the umblicus is inside the enclosure along with the Lindy cart. M1 homed and relaxed M2 homed DA checked out. Imager and spectrograph biases taken, but no spectrograph focus check done. Night: Rain continued through the night preventing opening. Shakedown items completed: - sdssProcedures v1_79: looks ok with minor comments: 1) The edit to the afternoon checkout procedure introduced a new typo. "goDrift -bias -autoScale" was changed to "goDrif -bias". We lost a "t". 2) Mike made edits to the telescope limits cheat sheet. They look right, but I'm just wondering why the 15-degree stop limits aren't included. Mike? The remaining shakedown tests require opening. During the night, we found an inordinate amount of water at the west end of the upper enclosure and flowing through the floor into the lower enclosure. We swept and shop-vac'ed up a lot, but there was still a large quantity running down onto the PMSS/FF lamp PSU rack (north of west rack). Although the plastic sheeting over the rack was protecting the PMSS, we were very concerned about water getting into the FF lamp PSU, so we switched it off and unplugged it from its main power socket. In the upper enclosure, water is running _under_ the doghouse. We did not open the doghouse to look inside, as the enclosure humidity sensor was already reading 80%. The light and other electrical fittings on the ceiling of the lower enclosure were catching a lot of water, too, so beware of lighting failures. We also used the last of the 3M absorbent blankets - are there more on site? We spoke with Wendell (Carlos mdid not answer and may be on the road to APO) to ensure the day crew know of the problem. We tried opening the west door slightly and closing it hard but it's not clear if that is the source of the problem. Is is possible water is coming in _under_ the upper aluminum floor? Perhaps the west door needs "eaves" on its lower edge to direct water out to the west grating. A PR is being filed. At least the Shop-Vac has been cleaned of moths! ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4238 22:48Z 23:13Z 100 O 103.94 110.07 55 ignore doghouse ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): Y QA Procedures Done (y/n): N UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 23255, plate -9999 ------- 22:45 23255 0.0 bias 00:47 23256 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- No tapes to ship - endNight run onto the "cloudy night" tapes. ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Earlier data not recorded, perhaps because we did not have a logTool running.

The nominal values are also out of date, so all we are proving here is that we can drive the mirror to the wrong position!
